“…The only 1 peak appeared because that there was only 1 chemical environment for the nitrogen element in cyano groups. However, the N 1s XPS spectra of the P (AN‐MAA) treated at high temperature were divided into 2 peaks around 398.9 and 399.6 eV (see SMI‐3 in the Supplementary Information), which could be assigned to the cyano and imide peaks . The results illustrated that the imide groups had been formed during thermal‐treated process.…”

The polymethacrylimide/silicate (PMI/silicate) composites were successfully prepared from the monomers of acrylonitrile (AN) and methacrylic acid (MAA) via the monomer in situ intercalation polymerization and free foaming. The formation of imide groups was monitored by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The results of FTIR and XPS indicated that the imide groups were gradually formed and cyano groups were dwindling but still existed during foaming and thermal treatment. The thermogravimetric analysis results revealed that the thermal stability of the PMI/silicate composites was improved, the rate of thermal degradation was reduced, and the residue was increased because of the addition of silicates. The results of dynamic mechanical analysis revealed that the rigidity and the glass transition temperature of the composites were improved.The limit oxygen index (LOI) and cone calorimeter (CONE) test showed that the fire-retardant properties were improved because of the barrier effect of silicates.The cell morphologies of the PMI/silicate composites were characterized by scanning electron microscopy (SEM), and the results showed that the silicate particles were distributed on the cell walls, but the cells slightly cracked. The mechanical properties were measured by tensile, flexural, and compressive strength. The mechanical strength, especially flexural strength, was significantly improved. The flexural strength of PMI/MMT, PMI/kaolin, and PMI/talc containing 8 wt% silicates was improved to 172%, 240%, and 233%.

“…Graphene has excellent thermal stability and excellent flame retardancy. In order to solve the problem of high flammability and large amount of smoke produced by epoxide resin, (Liu et al 2016)obtained ZHS/RGO hybrids with higher flame retardancy by in-situ hydrothermal method, which was used as a flame retardant and smoke suppressant and added with epoxide resin; In order to solve the problem of poor dispersibility of pure graphene in the polymer matrix, graphene oxide was used as flame retardant and smoke suppressing synergist, waterborne acrylic emulsion as film forming material, titanium dioxide as pigment and formulated an intumescent waterborne fire retardant coating and studied its flame retardant and smoke suppression effects using a large plate combustion method, a cone calorimeter and a smoke density test method (Li Hongfei et al 2015); A high-density PE/brominated polystyrene/graphene nanosheet composite was prepared with good dispersibility and became a flame retardant composite with excellent performance by melt blending method (Ran et al 2015); Graphite oxide (GO) and a hyperbranched flame retardant containing nitrogen and phosphorus was functionalized, and then the obtained functional graphene oxide (FGO) was introduced into the cross-linked polyethylene(XLPE) to enhance the flame retardancy of the matrix (Hu et al 2014); The effects of different particle sizes and shapes of carbon additives on the flame retardancy and mechanical properties of isotactic PP were studied in (Dittrich class Group 2013); An intumescent flame retarder (IFR), carbon nanotubes (CNTs) and graphene were incorporated into the PP matrix to prepare a new PP nanocomposites (Huang et al 2014); The surface hydrophobicity of graphene was changed by functionalizing the surface functionalized graphene oxide (FGO) grafted with pentaerythritol (PER) in water, and then introduced FGO into the intumescent flame retardant polypropylene system (Xu et al 2016); GO-modified N-containing organic zirconium phosphate was nano-composited with PP and evaluated its flame retardancy (Nie et al 2015); A covalently grafted FGO/PP nanocomposites with better flame retardant properties was reported in (Yuan et al 2014).…”

“…Halogen‐free inorganic flame retardants are promising because of their low smoke production and low toxicity during combustion . Flame retardants, such as zinc hydroxystannate, metal oxides, metal hydroxides and metallic ferrites, are commonly used as flame‐retardant additives in PVC composites, leading to good flame retardancy . Among these flame retardants, metal oxides are attracting increasing attention because of their advantages, such as excellent flame retardancy and thermal stability .…”

A wood flour/polyvinyl chloride (WF/PVC) composite with poplar veneer as the surface layer (veneered WF/PVC composites) was prepared by hot pressing. To improve the flame retardancy of the veneered WF/PVC composites, a self‐developed flame retardant of wood (FRW, composed of guanylurea phosphate [GPU], boric acid and few additives) was impregnated in the poplar veneer, and zinc oxide (ZnO) was incorporated into the WF/PVC composites. Properties of the composites, including thermal decomposition, flame retardancy, interface adhension strength, impact strength and flexural properties, were investigated. Thermogravimetric analysis (TGA) showed that the FRW and ZnO accelerated the pyrolysis of the composites in the first stage and had a positive effect on thermal performance at high temperature. Cone calorimetry showed that the FRW and ZnO promoted the rapid formation of carbon and had a positive effect on the flame retardancy and smoke inhibition properties. The mechanical results showed that a strong interface adhension strength was formed between the surface poplar veneer and PVC composite board substrates. The poplar veneer significantly improved the impact and flexural properties of the WF/PVC composites.
